JAVA Platform Based On The Safety Of Analysis And Research

Internet makes Java into the most popular program language in the network, while Java exacts a profound influence on Internet. Accompanied with the population and deep going of Java application, the security of information becomes one of the important questions people in various fields pay universal attention to. As a mature technique day by day, Java's security and transplant ability are especially outstanding.It is exactly in view of the superiority of the security of Java platform that the developing and researching programs, with the aid of Java platform, come out uninterruptedly. This essay, based on the analysis and research of Java platform security, makes use of Java platform to supply An Implement of Security Middleware In Electronic Commerce. The principal content is as follows.(1) Starting with the network security angle, this article analyses the importance the information security and the current situation of Java platform safety and introduces the knowledge such as digital signature ,certificate ,and PKI etc. and the relative knowledge of cryptography such as one-way hash function, symmetry cipher and asymmetry ciphers etc..(2) The problem is put forward which mobile code security evolves in secure Java system. It is an important target of Java platform to improve constantly the security of mobile code. Accompanied with the process that the security model of Java platform evolves consistently, the security of mobile code is raised and so is the easy-usability to the questions such as safety operation and disposition.(3) It is one of characters of Java platform to variously extend on the core of security infrastructure and respectively define the standard API to different application. So that it makes it become very convenient to develop secure applications on the Java platform. This article analyses and researches Java security infrastructure and its relative important extensions; looks into the integral structure of safety system; analyses and researches in detail various extensions of Java platform such as JCE, JSSE, JAAS and the research on implementing the principle of mechanism.(4) Based on the superior requirement of Electronic Commerce in security, this theme proposes a scheme of security middleware in E-commerce. Basing on Three-layer Structure, the scheme proposes a logic infrastructure of signature and encryption in E-commerce; provides the details of the implement of the middleware and design the universal API. The scheme is based on the Java 2 security platform and its secure extensions, makes fully use of the mature security infrastructure PKI. Our scheme provides a total solution of the security problems on the application layer, integrates key management, cryptographic services and hardware devices.Overall, this theme starts with the security angle of the network and carries out the research on various respect of the preceding Java platform security. This essay provides the feasible implement mode and the principle in the signature and encryption of An Implement of Security Middleware In Electronic Commerce by using Java platform. By means of the design for Middleware, our scheme improves the performance of the security operations by using hardware devices; the integrated form is supplied to different equipments and operation systems so that the security of Electronic Commerce is improved; the development process of Electronic Commerce simplified and the difficult degree of development decreased. Owing to the Middleware is a very extensive concept, what is implemented in this article only involves safety operation. This essay hasn't discussed other functions too much. So there is still very expansive room. The implementation mode in this theme is of definite value of theory and application.
